Aflltcatton tiled November 18, 1911. Serial No. 861,000.

To all whom it may concern: .f

Be it known that I, S'rsrnsN S. Kaarsa, a citizen of the United States of America, and resident of the city of St. Louis and State of Missouri, have invented certain new and useful Im rovements in Means for Supplying Explosive Mixture to Explosive-Engines, of which the followin 1s a full, clear, and exact description, re erence in being had to the accompanying drawings,

forming part of this specification.

My invention relates to a device intended to be used as an auxiliary to-the main carbureter and explosive member supplying device of an explosive engine, t rough the medium of WillCilMl initial quantity of explosive mixture may be delivered to the cylinder, or cylinders, of the engine, for the purpose of providing for the engine bein a0 started wit out resorting to the usua cranking operation.

Figure I is a view partly in elevation and partly in section, illustratin my improvement. Fi II is an inverte plan view of 2a the air injector located in the auxiliary carbureter shell. Fig. 111 is an elevation of a modified form of air injector.

In the accompanyin drawingsz-A designates the cylinders 0 an 'ex losive engine.

so I have shown four of such cy inders, but it will be obvious that my improvement may be used in connection with any number of cylinders. Explosive mixture is delivered to said cylinders through branch pi as B lead- :ia ing from a manifold 0, common all of the branch-pipes. I

D designates a main carburetor that is ;placed in communication with the manifold C b a conducting pipe it through which exp osive mixture aerated in an ordina manner may be (I ivered to the manifol and therefrom to the engine cylinders. The main carbureter has associated with it a float chamber F, containi a, float .G 40 through ,the medium of whic the level of hydrocarbon oil in the main carburetor is controlled.

No invention or so is herein claimed for the parts thus ar described, they all being no common to old forms of devices for creating and supplying explosive mixtures to explosive engines.

1 desi ates the shell of my auxiliary carbureter, tween which and the float chamber F communication is established by a con- 5 nesting pipe 2 that provides for the delivcry 0 ydrocarbon oil from said float chamber to the interior of the auxiliary carbureter shell. Thefloat G controls the level of hydrocarbon oil in the auxiliary carbureter shell.

8 designates an explosive mixture conducting pipe leadin from the auxiliary carburetor shell to t e manifold C, and through which explosive mixture may be conducted 05 to said manifold to be distributed therefromto any one or more of the engine cylinders in which the parts are in proper positions to receive a charge of explosive mixture.

4 designates an air conducting pipe through which air under pressure may e led from any source of an ply to the interior of the carbureter shell, 1. The pipe 4 communicates with an injector 5 compris- 7o ing a coil having perforations therein, the perforations being preferably minute in size. The air injector coil is isposed horizontally in the carbureter shell 1 near the bottom of said shell, and its perforations so are preferably in the bottom of said coil, in order that air under ressure delivered into the injector and di'sc arged therefrom may be directed downwardly in the hdrocarbon oil to thereafter rise in the oil w ile becoming saturated with the volatile elements of the oil,

6 is a horizontal screen extending transversely of the auxiliary carburetor shell above the level of the drocarbon oil in 00 said shell, and through which the explosive mixture of air saturated with the volatile elements or fumes of said oil pass before enterin into the conducting i e 8 to pass there rom to the engine cyhn era that are to be supplied with explosive mixture. 1

At the point of communication between the conducting pipe E leadin from the main carbureter and the mani old 0 is a check valve 7 that opens inwardly within said manifold and is normally held from its sent by a spring 8. This valve is adapted to in my anxiliarycarbureter, an

vide for the automatic closing the opening of the valve 11,

.in operation preparatory to t he closed to shutoff communication between the manifold-and the main conducting pipe 1' when explosive mixture is bein nerated cing de- To proof said valve, I arrange within the manifol C a T-shaped nozzle 9 directed at one end toward the check valve 7, and at the other end toward the outlet from the manifold. It will be obvious that this construction may provide for the'delivery of ex losive mixture toward and against the chec valve with sufiicient pressure to move the valve to its seat against the action of the s ring 8 thereby providing the passage of tiie explosive mixture delivered from the auxiliary carbureter to the conducting pipe of the main carbureter.

and 11 are cut 08 valves that respectively control the flow of hydrocarbon oil through the pipe 2 and air under pressure throu h the pipe 4. These valves are connector? in common to an operating rod 12, by which they may be actuated in unison, and the valves are so arran ed that when one of them is o ened, the ot or is closed.

In Fig. III. have shown a modification of the air injector in the shell of my auxiliary carbureter, this modification com rising a rose 5' that may be used in lieu o the coil 5.

In the practical use of my improvement, the operation is as follows: Assuming that the auxiliary carbureter shell 11 contains'a livered to the'engine cylinders A.

supply of hydrocarbon oil, as illustrated in the drawin s,- an initial supply of ex losive mixture is clivered to the engine cy inders .101

7 medium 0 the operating rod 12, whit: ma

by openin the air pipe valve 11 throu h the be manipulated in any suitable manner, an

the operation of which causes the valve 10, controlling the outlet 2, to be closed. Upon air under prea- .-ure is admitted to the injector t5 and dischar ed therefrom into the hydrocarbon oil in w iich the injector is submerged. The air being dischar d from the in ector under pressure circu ates rapidl in the oil and becomes impregnated with e volatile and explosive elements of the all while assin up- \vurdly theiethrough. As the sa urate air, or what'is then an ex losive mixture, rises above the surface of t a hydrocarbon oil, it passes throughthe screen and is delivered (y the conducting ipe 8 into the manifold and finally to tie engine cylinders that are to be supplied with explosive mixture preparatory to ignition of t 0 mixture for the purpose of p aclng the en ne initially 0 supply of explosive mixture thereto from the main carbureter. When sullicienti supply of explosive mixture has been created in the auxiliary carbureter and delivered to the eng ne cylinders to start theen inc, the operating rod 12 is manipulated or the purpose of shutting off the flow of air under pressure through the pipe 4 and reestablishing commui'iication between the float chamber F and the auxiliary carbureter shell by opening the valve 10, in order that the supply of hydrocarbon oil in said shell may be replenished.

I claim 1. The combination with an explos ve engine and a main carbureter for supplying explosive agent to said engine, of a starting device comprising an auxiliary carbureter shell having communication with said main carbureter and with a cylinder of said enginc, an air injector submerged in the explosive agent contents of said shell, means jector. and simultaneously operable means whereby the passageway in said air delivery means is opened and the passageway between said auxiliary and main carburetors is closed.
